This priceless movie is one of the most entertaining pieces of wartime hokum ever put on film. I can't say much about the storyline without risking giving away the whole movie. Let's just say that a very mysterious foreigner comes to stay at the house of a doctor in Washington, during the Second World War, and arouses great curiosity among everyone he meets. A group of supposedly respectable businessmen are actually involved in Fifth Column sabotage of the American war effort, and the cryptic Monsieur Colomb is bumping them off, one by one, for reasons of his own. This movie is an absolute gas, with a lot of deliberate humor. Lugosi has many great sinisterly funny lines, and it's truly one of his best roles in Forties B pictures. He seems to be having great fun throughout the movie, and revels in his villainy so much that the viewer can't help but cheer him on. There's even a surprising hint of sexuality that's very rare for an old movie, just lightly suggested, but nonetheless there. The pretty young niece of the doctor is intrigued by Lugosi and flirts with him in one scene, where he seems tempted to have a brief romance with her. The stalwart FBI man played by Clayton Moore ( later television's Lone Ranger) is interested in the girl and a bit jealous of her attraction to Lugosi. This film is just so much fun, every lover of old serials and Forties wartime morale-boosting movies should see it. For Lugosi fans, this is one of his most enjoyable performances. Check it out!
